  15DESCRIPTION
  16-----------
  17
  18Updates remote refs using local refs, while sending objects
  19necessary to complete the given refs.
  20
  21You can make interesting things happen to a repository
  22every time you push into it, by setting up 'hooks' there.  See
  23documentation for linkgit:git-receive-pack[1].

  26OPTIONS
  27-------
  28<repository>::
  29        The "remote" repository that is destination of a push
  30        operation.  See the section <<URLS,GIT URLS>> below.
  31
  32<refspec>::
  33        The canonical format of a <refspec> parameter is
  34        `+?<src>:<dst>`; that is, an optional plus `+`, followed
  35        by the source ref, followed by a colon `:`, followed by
  36        the destination ref.
  37+
  38The <src> side can be an
  39arbitrary "SHA1 expression" that can be used as an
  40argument to `git-cat-file -t`.  E.g. `master~4` (push
  41four parents before the current master head).
  42+
  43The local ref that matches <src> is used
  44to fast forward the remote ref that matches <dst>.  If
  45the optional plus `+` is used, the remote ref is updated
  46even if it does not result in a fast forward update.
  47+
  48Note: If no explicit refspec is found, (that is neither
  49on the command line nor in any Push line of the
  50corresponding remotes file---see below), then "matching" heads are
  51pushed: for every head that exists on the local side, the remote side is
  52updated if a head of the same name already exists on the remote side.
  53+
  54`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
  55+
  56A parameter <ref> without a colon pushes the <ref> from the source
  57repository to the destination repository under the same name.
  58+
  59Pushing an empty <src> allows you to delete the <dst> ref from
  60the remote repository.
  61
  62\--all::
  63        Instead of naming each ref to push, specifies that all
  64        refs under `$GIT_DIR/refs/heads/` be pushed.
  65
  66\--mirror::
  67        Instead of naming each ref to push, specifies that all
  68        refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
  69        be mirrored to the remote repository.  Newly created local
  70        refs will be pushed to the remote end, locally updated refs
  71        will be force updated on the remote end, and deleted refs
  72        will be removed from the remote end.
  73
  74\--dry-run::
  75        Do everything except actually send the updates.
  76
  77\--tags::
  78        All refs under `$GIT_DIR/refs/tags` are pushed, in
  79        addition to refspecs explicitly listed on the command
  80        line.
  81
  82\--receive-pack=<git-receive-pack>::
  83        Path to the 'git-receive-pack' program on the remote
  84        end.  Sometimes useful when pushing to a remote
  85        repository over ssh, and you do not have the program in
  86        a directory on the default $PATH.
  87
  88\--exec=<git-receive-pack>::
  89        Same as \--receive-pack=<git-receive-pack>.
  90
  91-f, \--force::
  92        Usually, the command refuses to update a remote ref that is
  93        not an ancestor of the local ref used to overwrite it.
  94        This flag disables the check.  This can cause the
  95        remote repository to lose commits; use it with care.
  96
  97\--repo=<repo>::
  98        When no repository is specified the command defaults to
  99        "origin"; this overrides it.
 100
 101\--thin, \--no-thin::
 102        These options are passed to `git-send-pack`.  Thin
 103        transfer spends extra cycles to minimize the number of
 104        objects to be sent and meant to be used on slower connection.
 105
 106-v, \--verbose::
 107        Run verbosely.

 111OUTPUT
 112------
 113
 114The output of "git push" depends on the transport method used; this
 115section describes the output when pushing over the git protocol (either
 116locally or via ssh).
 117
 118The status of the push is output in tabular form, with each line
 119representing the status of a single ref. Each line is of the form:
 120
 121-------------------------------
 122 <flag> <summary> <from> -> <to> (<reason>)
 123-------------------------------
 124
 125flag::
 126        A single character indicating the status of the ref. This is
 127        blank for a successfully pushed ref, `!` for a ref that was
 128        rejected or failed to push, and '=' for a ref that was up to
 129        date and did not need pushing (note that the status of up to
 130        date refs is shown only when `git push` is running verbosely).
 131
 132summary::
 133        For a successfully pushed ref, the summary shows the old and new
 134        values of the ref in a form suitable for using as an argument to
 135        `git log` (this is `<old>..<new>` in most cases, and
 136        `<old>...<new>` for forced non-fast forward updates). For a
 137        failed update, more details are given for the failure.
 138        The string `rejected` indicates that git did not try to send the
 139        ref at all (typically because it is not a fast forward). The
 140        string `remote rejected` indicates that the remote end refused
 141        the update; this rejection is typically caused by a hook on the
 142        remote side. The string `remote failure` indicates that the
 143        remote end did not report the successful update of the ref
 144        (perhaps because of a temporary error on the remote side, a
 145        break in the network connection, or other transient error).
 146
 147from::
 148        The name of the local ref being pushed, minus its
 149        `refs/<type>/` prefix. In the case of deletion, the
 150        name of the local ref is omitted.
 151
 152to::
 153        The name of the remote ref being updated, minus its
 154        `refs/<type>/` prefix.
 155
 156reason::
 157        A human-readable explanation. In the case of successfully pushed
 158        refs, no explanation is needed. For a failed ref, the reason for
 159        failure is described.

 161Examples
 162--------
 163
 164git push origin master::
 165        Find a ref that matches `master` in the source repository
 166        (most likely, it would find `refs/heads/master`), and update
 167        the same ref (e.g. `refs/heads/master`) in `origin` repository
 168        with it.
 169
 170git push origin :experimental::
 171        Find a ref that matches `experimental` in the `origin` repository
 172        (e.g. `refs/heads/experimental`), and delete it.
 173
 174git push origin master:satellite/master::
 175        Find a ref that matches `master` in the source repository
 176        (most likely, it would find `refs/heads/master`), and update
 177        the ref that matches `satellite/master` (most likely, it would
 178        be `refs/remotes/satellite/master`) in `origin` repository with it.
 179
 180git push origin master:refs/heads/experimental::
 181        Create the branch `experimental` in the `origin` repository
 182        by copying the current `master` branch.  This form is usually
 183        needed to create a new branch in the remote repository as
 184        there is no `experimental` branch to match.
